I have an Artisan 50 (Epson's replacement for the R260) and while it does make nice prints and is convenient to have for "instant" photos, even with the proper color profiles and Epson's premium photo paper, it is still VERY obvious which photos come from that printer and which come from Adorama. Enough so that even my kids (4 and 7 years old) tell me that the lab prints look better.
Looks like you didn't calibrate your printer properly, then. The R260 is most definitely capable of prints that rival a pro lab. I can't tell you how many prints I have "improved" with Photoshop and my consumer grade R260.
This thread is annoying me. While it is valuable to have excellent photo professionals to draw info from, their opinions are skewed. The digital age has crushed many, many professional photographers. The ease at which a a customer can take a snapshot or scan and reprint, in obvious violation of copyright laws, has just about made it impossible to make a good living for anyone but the top 10% of photographers out there. The only way to fight back is to permeate the myth that the home user just can't make good, professional quality prints. It can be done, but it's not easy and I don't recommend it for average joe off the street.
Someone at home can print photos that will rival a professional photo lab. However, it requires knowledge, an investment beyond a basic AIO printer and time... lots and lots of time. If you are willing to spend the time to develop a good color workflow and will take the time to calibrate your monitor and develop the right .icc profiles for the scanner and printer then there's no reason that you couldn't go to Officemax and pick up all the supplies you need to make 11x14 prints that rival a photo lab. That's where the knowledge thing comes in; they won't know enough to get a calibration device or to have professional profiles created. Jane Doe doesn't know what color gamut or black point compression are. She won't even know that she doesn't know what they are.
What the public should know is that for 99% of the population it won't be worth the time or effort and it can be done more cheaply by a lab for anything but 8x10 and up. Anyone that prints more than a couple for 4x6 prints at home is crazy when you can have Walgreens do it for $.12 each.
So, that being said..... unless OP is willing to drop $1000 on an Epson 1400, a monitor that can be calibrated, a V500 scanner and wants to throw away $100 worth of ink and paper just to create a solid workflow for each ink/paper combination then he should just go to a lab. $1000 can buy a lot of work from a Pro. Adorama is awesome.
Except for a couple of exceptions, amateur's should NOT do black and white. I will take that one to the grave.
Cliff's:
1 - Pro photographers can have their own agendas. Be careful what advice you take on this topic.
2 - With a $1000 and 100 hours, someone at home can buy equipment at an office supply store and make prints at home that rival a lab
3 - It's far cheaper to have 4x6 done by a Walgreens or something similar. They're too small to see real results from a lab. 8x10 up is the only way to recoup any investment.
4 - B&W is best left to professionals
5 - Adorama has a great lab
